The Smart key on my 2004 Toyota Prius locked the doors on its own, even while in the car. I unlocked the doors with the Smart key, placed my baby in his carseat, buckled him in, placed his diaper bag on the floor in the backseat as always, with the Smart key in a pocket of the diaper bag, and as I was closing the back door so that I could get in the driver seat, all of the doors locked on their own. The Smart key was in the diaper bag inside the car, as was my baby, and I could not get into the car. I had to call my wife and have her bring the second Smart key to unlock the door. Luckily my baby was not freaking out, and it was not a hot day. It was an extremely dangerous and scary situation.
